To all whom it may concern:

Be it'known that I, FRANK L. SHOPPE, a citizen of the United States, residing at Ramsey, in the county of Bergen and State of New Jersey, have invented new and useful Improvements in Flush-Tank Valves, of which the following is a specification.

The invention relates to valves and more particularly to valves for flush tanks. It aims .to provide a flush tank valve that is positive in its seating action thereby'eliminating the unpleasant noises due to a faulty seating of the valve.

An object of the invention is the provision of a novel form of valve and seat whereby. the valve will accommodate itself readily to any irregularities of the seat due to the wear on the same, in order to insure a perfect seating thereof. a

Another object of the invention is the provision of a valve of novel formation constructed so that the same is of varying diameters throughout its height.

A further object of the invention is the provision of a seat of a formation that readily accommodates itself to the different or varying diameters of the valve.

A further object of the invention is the provision of a novel form of cage or guide 'for the valve together with a lifting means I for the valve which while insuring a per-' fect seating of the valve, allows the same, a certain amount of free movement independent of the guiding means.

Other objects and advantages of the structure will be apparent as the nature A and operation of the invention is better understood from a reading of the following description and claims taken in -connect1on with the appended drawings of wh1ch:- Figure 1 is a fragmentary sectional view of a flush tank, showing the valve-seat and the parts associated therewith in sectlon.

Fig. 2 is a perspective view of the invention as an entirety.

Fig. 3 is a plan vlew of the invention.

Fig. 4 is a perspective view of the valve with the lifting element operatively associated therewith.

Fig. 5 .is a detailperspective view ofthe valve seat.

In the drawings, I have shown a conventional form of 'afiush tankwhich is represented; at A, provided with a valve lifting means B, which maybe of any well known construction. The outlet-pipe shown at C,

is provided with the usual flange D, and'the by-pass E, into which is threaded the pipe F. Formed at the top of the outlet-pipe C, is a flan e 10, which is in the form of an annular ead which is adapted to enter the groove 11, in the valve-seat 12. Said valve seat is of conical formation and reduced at its upper end. The upper portion of the outlet-pipe C, 1s exteriorlythreaded to receive the 'interiorly threaded boss 13,. of

the cage support 14, said cage support is provlded with an inwardly extending an- ,nul'ar flange 15, which is adapted to en age the upper extremity of the flange 16, 0 the valve so as to adjust the-reduced mouth of the same in order to take up any wear upon said valve. The cage is composed of the upright rods 17, and the ring member 18, which is provided with sockets 19, adapted to receive the upper extremity of the rods 17 the lower ends of which are secured in the cage-support 14. One of the rods 17, is extended through the ring 18, and threaded.

to receive'the securing nuts 20, which are disposed on either side of the ring. This construction enables the valve to be easily removed and a new one placed therein in case of breakage; The valve is shown at 21, and in outline simulates an ordinary electric bulb with the smaller end disposed in downward relation to the seat. Provided upon the'lower end of said valve is a guide rod 22,

which loosely works in the spider 23, to prevent the valve moving to one side of the same and preventing a positive seating of the valve. The ring l8,is provided at the opposite sides thereof, with elongated guides 24, through which the arms of the lifting element 25, slide. The. lifting element is provided at its lower end with a ring 26, which is adapted to contact with the enl'arged portion of the valve and lift the same from the seat. The upper cross-bar 27, of

the lifting element is provided centrally thereof with an eye 28, to which is secured the link 29', said link 29, is loosely engaged at its upper end to the hook portion of the lifting means B.

I It .will be particularly noted from the peculiarities of construction that the restricted end of the valve seat is capable of certain downward movement, while the opening at said restricted end is free to respectively be distended and contracted during adjustment of the valve against the seat. As a consequence thereof, the seat always adapts itself to all inconsistencies inv the movements of the valve and positively responds yieldingly to the difi'erent diameters-of the valve, so as to maximize the sealed condition of the joint the small end thereof.

as the valve enters the seat.

It will be particularly noted from the peculiarities of construction that the guide rod 22, and the weight of the valve constitute means or a mechanism for gravitationally insuring a projection bodily of the valve into the seat so as to augment action of the seat to expand and automatically ancommodate itself to the eXternaLdiameter of the valve.

-What is claimed as new is 1. A valve structure comprising an elastic valve seat, having an opening whose diameter decreases toward the upper end of said seat, and a valve movable into said opening and against the walls of the seat at the restricted. end, of the opening, the weight of the valve serving to move the seat slightly in a downward direction as the valve enters the seat whereby to set up an active impingement-of the walls of the seat against the walls, of the valve at the upper end of memos the former, the valve having a prominent taper throughout and provided with a restricted end whose diameter is appreciably less than the normal diameter of the seat at 2. A valy e structure for flush tanks, comprising, in combination with a seat and a co-ac'ting inverted tapering valve associated with the seat and having its restricted end normally projecting through the seat, a rod depending from the restricted end of the valve, a fixed guide member located beneath the seat and freely receiving said rod and serving to guide the valve in its movements relatively to the seat, a cage in which the valve is freely movable, and a lifting device slidable in the cage and having a base portion freely embracing the valve and adapted to co-act therewith to lift the same from the seat, the diameter of said base portion being greater than the adjacent diameter of the lower end of the valve whereby to permit the latter to descend in the direction of said seat I in testimony whereof I affix my si nature. 1 FRANK L.
